giiyanman Posted January 24, 2019 Share Posted January 24, 2019 Hi all, I recently got some work done on my intake manifold (fuel leak in one of the houses under the manifold). Before getting the work done I could only hear the turbo spooling (high pitched sound) from inside the cabin. I thought that was normal since the car is totally stock and does not come with flashy blow-off valves that give that classic turbo whistle. After getting the car back yesterday, I immediately noticed a more pronounced turbo sound. I have been hearing a more "windy" sound from the turbos, similar to how jet engines sound when they wind up and inhale air... There is also a sound similar to that of a BOV when I upshift, even though JDM Legacy's are supposed to come with EGR valves.. So I guess my question is: to everyone who owns a turbo Legacy (USDM or JDM), what should I hear coming from my turbos? If it is completely stock, should I be hearing these sounds? Or should I take it back to the garage for them to recheck their work? Link to comment Share on other sites More sharing options...
AgentSmith Posted January 27, 2019 Share Posted January 27, 2019 Hearing the turbos maybe ok. If it is stock, it should be a little quieter. However if the car is driving fine and you have your full boost then enjoy your boosted vehicle. If you haven’t invest in a boost gauge to monitor your system.
